Rush Strategy
In normal mode, one common strategy is to make 2 stacks of 3 pieces and 1 stack of 2 pieces, then rush through the river. At this stage of the game, to traverse the river, you usually have to drop down the top piece of a stack of 2 or more on the river from the allies side. This creates a "passerelle" that allows pieces of any side to traverse without droping down on the river. The stack of 2 is used to create a passerelle in this strategy.
Once the stack of 2's top piece has fallen on the river, the 2 stacks of 3 can advance on each side of the passerelle just created.
A common organisation of the pieces is constructing the stack of 2 in the middle and the stacks of 3 on the direct sides of the stack of 2.
When arriving on the other side of the board, the idea is to use the jumping mechanics to take control over the opponent. With the 8 pieces brought to the other side, it is possible to jump at least 2 times in a row, and possibly a 3rd time. The latter is made possible by bringing the original bottom piece of the stack of 2 on top of the piece in the river, therefore making a new stack of 2. This new stack can then be used to create another stack of 3, which is then used to jump a 3rd time.
drawbacks
Some drawbacks of this strategy is that it can be countered. All the opponent has to do is wait with 2 stacks of 3 ready to defend (so at a distance of 1 from each other).
